Questione giuridica chiave
Whether the federal complaint could be directed against the lower cantonal supervisory decisions
Decisione estratta
The complaint may only allege violations by the higher cantonal supervisory authority; direct challenges to the lower authority's decisions are inadmissible.
Motivazione estratta
Under Art. 19 SchKG, grievances must be addressed to the upper supervisory authority, so only the cantonal court decision could be attacked before the Federal Supreme Court.
